Between 1405 and 1433, the Ming government sponsored a series of seven naval expeditions. The Yongle emperor designed them to establish a Chinese presence, impose imperial control over trade, impress foreign peoples in the Indian Ocean basin and extend the empire's tributary system.<br/><br/>

Zheng He was placed as the admiral in control of the huge fleet and armed forces that undertook these expeditions. Zheng He's first voyage consisted of a fleet of up to 317 ships holding almost 28,000 crewmen, with each ship housing up to 500 men.<br/><br/>

Zheng He's fleets visited Arabia, Brunei, East Africa, India, the Malay Archipelago and Thailand, dispensing and receiving goods along the way. Zheng He presented gifts of gold, silver, porcelain and silk; in return, China received such novelties as ostriches, zebras, camels, ivory and giraffes.

Face Reading is one of the most ancient tools used for diagnosis in Chinese Medicine. Because palpation of the body was not a common practice, especially when treating women, the face became one of the easiest places to access the signs of internal organ function.<br/><br/>

In the oldest manuscript of acupuncture ever discovered so far, Dr. Paul Unschuld of Germany found that the first page of this manuscript was a facial map containing 150 age positions while the second page was a diagram of the facial meridians. This same facial map is still in use today and is used to find the ages when trauma occurred that still affects current psychological and physical health. This map can best be described as a topographical representation of life experience.
Chiropractic is a form of alternative medicine that focuses on diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine, under the belief that these disorders affect general health via the nervous system.<br/><br/>

The main chiropractic treatment technique involves manual therapy, especially manipulation of the spine, other joints, and soft tissues, but may also include exercises and health and lifestyle counseling.

Around 2000 years ago, Chinese in Sichuan province originated deep drilling. The primary motive for deep drilling in China was the search for salt. Even as recently as 1965, 16.5% of China’s salt supplies came from brine pumped out of deep boreholes, making this source of supply second only to sea salt.<br/><br/>

The ancient percussive cable drilling system was called 'churn'. The derrick had a height of 11m and all parts of the rig were made from wood (mainly bamboo). A large wooden drum, 5m in diameter, was used to raise and lower the drill. A rocking movement of the balancing beam created the percussive impulses on the bit, which sometimes weighed as much as 140kg. By alternately lifting this tool and letting it fall, the Chinese could achieved a well depth of 600m.<br/><br/>

The deep drilling for brine yielded natural gas (primarily methane) from time to time. The boreholes producing methane were known to the Chinese as 'fire wells', thus drilling for natural gas followed and was developed at the same time.<br/><br/>

Bamboo tubes were used as pipelines, carrying both brine and natural gas for many miles, sometimes passing under roads and sometimes going overhead on trestles. Among other uses, natural gas was used to heat evaporation pans of brine to make salt.

Cai Lun (ca. 50 CE – 121), courtesy name Jingzhong, was a Chinese eunuch and political official. He is traditionally regarded as the inventor of paper and the papermaking process, in forms recognizable in modern times as paper (as opposed to papyrus).<br/><br/>

Although early forms of paper had existed in China since the 2nd century BCE, he was responsible for the first significant improvement and standardization of paper-making by adding essential new materials into its composition.
Materia medica (English: medical material/substance) is a Latin medical term for the body of collected knowledge about the therapeutic properties of any substance used for healing (i.e., medicines).<br/><br/>

The term derives from the title of a work by the Ancient Greek physician Pedanius Dioscorides in the 1st century CE, De materia medica, 'On Medical Material'. The term materia medica was used from the period of the Roman Empire until the 20th century, but has now been generally replaced in medical education contexts by the term pharmacology.
Qigong, qi gong, chi kung, or chi gung, literally 'Life Energy Cultivation') is a holistic system of coordinated body posture and movement, breath, and meditation used for health, spirituality, and martial arts training.<br/><br/>

With roots in Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed as a practice to cultivate and balance qi (chi) or what has been translated as 'life energy'.

The Wujing Zongyao or 'Collection of the Most Important Military Techniques' is a Chinese military compendium written in 1044 CE, during the Northern Song Dynasty.<br/><br/>

Its authors were the prominent scholars Zeng Gongliang, Ding Du  and Yang Weide, whose writing influenced many later Chinese military writers. The book covered a wide range of subjects, everything from naval warships to different types of catapults.<br/><br/>

Although the English philosopher and friar Roger Bacon was the first Westerner to mention the sole ingredients of gunpowder in 1267 (i.e. strictly saltpetre, sulphur, and charcoal) when referring to firecrackers in 'various parts of the world', the Wujing Zongyao was the first book in history to record the written formulas for gunpowder solutions containing saltpetre, sulphur, and charcoal, along with many added ingredients.<br/><br/>

It also described an early form of the compass (using thermoremanence), and had the oldest illustration of a Chinese Greek Fire flamethrower with a double-acting two-piston cylinder-pump that shot a continuous blast of flame.

Mancheng is the site of the Han dynasty tombs of king/prince Liu Sheng and his wife Dou Wan.
Astronomy in China has a very long history, with historians indicating that the Chinese were the most persistent and accurate observers of celestial phenomena anywhere in the world before the Arabs. Star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the middle Shang Dynasty (Chinese Bronze Age, 3rd - 2nd millennium BCE), and the mansion system's nucleus seems to have taken shape by the time of the ruler Wu Ding (1339-1281 BCE).<br/><br/>

Detailed records of astronomical observations began during the Warring States period (fourth century BCE) and flourished from the Han period onward. Chinese astronomy was equatorial, centered as it was on close observation of circumpolar stars, and was based on different principles from those prevailing in traditional Western astronomy, where heliacal risings and settings of zodiac constellations formed the basic ecliptic framework.
Mawangdui (Chinese: 馬王堆; pinyin: Mǎwángduī; literally: 'King Ma's Mound') is an archaeological site located in Changsha, China. The site consists of two saddle-shaped hills and contained the tombs of three people from the western Han dynasty (206 BCE – 9 CE), Marquis Li Cang, his wife, and a male believed to have been their son.<br/><br/>

The site was excavated from 1972 to 1974. Most of the artifacts from Mawangdui are displayed at the Hunan Provincial Museum. It was called 'King Ma's Mound' because it was initially (mistakenly) thought to be the tomb of Ma Yin (853–930), a ruler of the Chu kingdom during the Five Dynasties and Ten Kingdoms period.

A water clock or clepsydra (Greek) is any timepiece in which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel where the amount is then measured.<br/><br/>

Water clocks, along with sundials, are likely to be the oldest time-measuring instruments, with the only exceptions being the vertical gnomon and the day-counting tally stick. Where and when they were first invented is not known, and given their great antiquity it may never be. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon and in Egypt around the 16th century BCE.<br/><br/>

Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain. Some authors, however, claim that water clocks appeared in China as early as 4000 BCE.
Huangfu Mi  was a Chinese scholar and physician during the late Han Dynasty, Three Kingdoms, and Jin Dynasty period of Chinese history. He was born into a poor farming family in present-day Gansu province. Between 256 and 260, toward the end of the state of Cao Wei, he compiled the' Canon of Acupuncture and Moxibustion' (Pinyin: Zhēnjiŭ jiăyĭ jīng; Wade–Giles: Chen-chiu chia-i ching), a collection of various texts on acupuncture written in earlier periods.<br/><br/>

This book in 12 volumes further divided into 128 chapters was one of the earliest systematic works on acupuncture and moxibustion, and it proved to be one of the most influential. Huangfu Mi also compiled 10 books in a series called 'Records of Emperors and Kings'.

Acupuncture (from Latin, 'acus' (needle) + 'punctura' (to puncture) is the stimulation of specific acupuncture points along the skin of the body involving various methods such as penetration by thin needles or the application of heat, pressure, or laser light.<br/><br/>

Clinical practice varies depending on the country. Traditional acupuncture involves needle insertion, moxibustion, and cupping therapy. It is a form of alternative medicine and a key component of traditional Chinese medicine (TCM).<br/><br/> 

According to TCM, stimulating specific acupuncture points corrects imbalances in the flow of 'qi' through channels known as meridians. Acupuncture aims to treat a range of conditions, though is most commonly used for pain relief. It is rarely used alone but rather as an adjunct to other treatment modalities.
